[DAPHNE-daphne-eu#830] Fix anonymous namespace issue when compiling w…

…ith Clang

When compiling with clang, there is a issue at runtime (LLVM complaining about anonymous namespaces not allowed in various places). These are hereby replaced with a non-anonymous namespace. For the lack of creativity these are all called "file_local".
